Abstract Details

Purpose:

To expand upon and clinically demonstrate a recently published new polynomial decomposition method using programmed beta-software on the OPD-scan III wavefront aberrometer (Nidek, Gamagori, Japan).

Setting:

Institute of Laser Vision, Rothschild Foundation, Paris, France

Methods:

Theoretical considerations and the comparison between the qualitative and quantitative information produced by the Zernike and new series polynomial decomposition bases

Results:

The comparative studies validate the novel polynomial basis which decomposes the wavefront with clear segregation of the higher and lower aberrations, no artefactual reduction of some of the higher order aberrations coefficients and more clinically relevant retinal image quality.

Conclusions:

Some of the inherent limitations of the Zernike polynomials in clinical ophthalmology can be solved by a novel aberration basis.
